JACK FOR SOLE-MACHINES.

SPECIFICATION forming part of Letters Patent No. 461,403, dated October13, 1891.

Application filed September 8, 1890. Serial No. 364,222. (No model.)

To all whom it may concern.-

Beit known that I, GEORGE H. GoeswELL, of Bradford, county of Essex,State of Massachusetts, have invented an Improvement in Jacks forBeating-0ut Machines, of which the following description, in connectionwith the accompanying drawings,is a specification, like letters on thedrawings representing likeparts.

This invention has for its object an im- [0 proved construction of jack,whereby the sole of a shoe While the shoe is yet upon the last on whichit was last-ed may be beaten out or pressed into shape and the soleleveled.-

In accordance with my invention the jackstandard has a head providedwith a guideway for two carriages, one carrying a toe-rest and the othera counter or heelclamp, and a last-holding pin. The said carriages areconnected together in such manner that they may be moved toward and fromeach other in the said guideway according to the length or size of theboot or shoe being acted upon. The construction of the parts of thetoe-rest is such that when the jack is adjusted for a 2 5 certain lengthof shoe the toe-rest is also au tomatically adjusted vertically to thusplace the toe of the last in the proper position with relation to theform which acts on the sole of the shoe, the form and jack both movingin arcs of circles. The last-holding pin is made movable independentlyof the carriage which supports the counter or heel clamp, and the devicefor moving the heel-pin to jack, as it is called, the shoe into thecounter or heel 5 clamp is so placed and made that it may be actuatedautomatically by the form as it comes into position to act on the soleof the shoe.

Figure 1 in side elevation representsa suf- 4o ficient part of abeating-out or sole-leveling machine embodying my invention to enablethe same to be understood; Fig. 2, a partial left hand end view of theparts shown in Fig. 1; Fig. 3, a partial righthand end View of the same;Fig. at, a section in the line 0;, Fig. 1,

looking upwardly; Fig. 5, a detail of the carriage, having thelast-holding pin and heelclamp; Fig. 6, a detail in section, showing thetoe-rest, its carriage, and locking device. Fig. 7 represents myinvention embodied in a solelocking machine.

Referring to the drawings, (see Fig. 7,) the spindle A, the segmentaltoothed lever D connected to it, the sole molding or pressing form E,the leg E, the toothed segment-lever E the shaft E the worms E and D,and the means to rotate the said shaft E to turn the .to the upper endof the spindle'A a head A,

having its upper side out out to leave a guideway in which may fit andslide the carriages B and O, the said head having suitable slots,

as a a, through which are extended, respectively, the shanks b c of thesaid carriages, the said shanks having connected to them, respectively,the rack-bars b c, which mesh with a common pinion d loose on a stud atthe under side of the head, (see Fig. 4,) the said racks engaging thesaid pinion at opposite sidesof its center, so that in case eithercarriage is engaged by hand and moved in the said guideway the othercarriage will be moved in unison with it for a little distance, but inan opposite direction, the said carriages being so made movable in orderthat the jack may be quickly adapted to lasts of the size to be used.

The carriage B has erected upon ita 1101- low post I) in which isdropped a locking device b (shown by dotted lines Fig. 1, and separatelyin Fig. 6,) the lower end of said locking device being wedge-shapedtorest on the teeth of alocking-block 12 said teeth having inclinedbacks and being so located that the locking device may slip over thesaid teeth when the carriage B is moved toward the spindle for a'shorterlength of shoe, the looking device dropping behind the teeth andpreventing the movement of the said carriage 5 in the opposite directionwhen the sole is being pressed.

The carriage B, by me called the toe-rest carriage, receives the shankof the toe-rest b suitably shaped to conform to the shape of ICC the topof the last. As herein shown, the shank of the toe-rest is terminated byan adin Fig. 6, into which maybe pushed awedgea toe-rest-lifting device.

shaped lifting-pin ewhenever it is desired to lift the lower end of thelocking device 19 above the teeth of the block b, as when it is desiredto pull the carriage to the right in Fig. 1, for a longer shoe.

The carriage 0, called the counter or heel clamp carriage, has erectedupon it a counter or heel clamp 0 preferably rigid and of suitable shapeto embrace the heel part of the upper. This carriage receives in it theslide-bar f, upon which is erected the-heel or last pin f, the saidslide being normally held by the spring f slightly away from the saidcounter or heel clamp. This slide has a se ries of holes or notches 6,in which may be inserted the wedge-shaped lower end of the jacking barg, adapted to slide vertically in a guidepost g, erected on the head A,the said bar being normally kept elevated by spiral or other spring 9connected at one end to a pin 7 of the post and at its other end to apin 8 of the bar. The head has pivoted upon it at 10 a lever 71, one endof which engages alifti'ng device 72, which when that end of the levernearest the toe-rest-is lifted causes the lifting device to act on thepointed end of the jacking-bar, then down in a slot 6 and elevate ituntil the wedge-shaped part of the said bar is above the top of theslide f, when the spring 9 completes the movement.-

It will be noticed that when the toe-rest carriage is moved to the left,(see Fig. 1,) as is the case when a shorter last is to be used, thelocking device is lifted, so that it acts as The inclined top of eachtooth of the block b is a little higher than the one to the right of itin Fig. 1.

In operation, the last having on it a shoe the sole of which is to bebeaten out or pressed or leveled to shape, is slipped over the heel pinf in usual manner, the operator having previously put the toe-restcarriage into the proper position for a last of the size to be used, theoperation of putting the said toerest carriage in place also positioningthe counter or heel clamp carriage and counter or heel clamp. Thecounter or heel part of the shoe touches, or nearly so, the counter orheel clamp. The machine will now be started and the spindle will bemoved to carry the shoe to the left, viewing Fig. 7, and in so doing thejacking-bar will be depressed, so that its wedge-shaped lower end willenter one of thenotches 6 of the slide f anddraw the said slide and itsconnected heel-pin ff toward the counter-clamp, and so as to firmlycrowd the heel of the upper into said counter or heel clamp, so that thelast will be held rigidly while the usual form E acts on the sole. Thejacking bar is depressed by a part of the form E or its carrier, as theform is about coming down upon the sole to be leveled, and the straightpart of the jacking-bar above its wedge-point enters the notch 6 of theslide f, the bar in such depressed position firmly looking the saidslide. I have described how the said bar may be lifted when the shoe isto be removed. In operation the same form will be used to beat out from2 to7 size shoes; but forlarger or smaller sizes the form has to bechanged, and as the'form and the spindle and last move in arc-shapedpaths it is necessary that the toe-rest be at different heights,according-to the size of the shoe, the

smaller the size the higher the toe-rest, and

vice versa, so as to bring the toe part of the shoe correctly up intothe form.

This invention is not limited to making the teeth of the block b ofdifferent height, and in practice it will be seen that one feature ofthe locking device and bar I) is to lock the carriages in adjustedposition with relation to the heel-pin.

I claim- 1. In a j ack for a sole-beating-out machine, the spindle, thehead, thelast-pin, and toothed block if, combined with a toe-restcarriage, a toe-rest, and alocking device intermediate the saidtoe-rest, and the said block, to operate substantially as described.

2. In a jack, alast-pin, ahead, atoe-rest carriage therein, abeveled-ended locking device, and a toothed block b combined with alifting device or pin for lifting the locking device, substantially asdescribed.

3. The head, the last-pin, the toe-rest carriage, the toe-rest placedtherein loosely and having the lower end of its shank provided with anadjusting set-screw, and a locking device upon which said set-screwrests, to opcrate substantially as described.

4. The head, the counter or heel clamp and carriage to support it, and atoe-rest, combined with a heel-pin f and notched slide f, looselymounted in the said carriage, and-the jacking-bar, to operatesubstantially as described.
